Valve Big Bag

Valve Big Bag: Automation and Dust Control

Valve big bag is a specialized FIBC design featuring spout systems at filling and/or discharge openings.

Indispensable solution for automatic filling lines, controlled discharge, and dust emission control.

Spout Types

Filling Spout (Inlet Spout)

Located at the top of the big bag.

• Diameter: Ø300-500 mm
• Length: 40-70 cm
• Use: Connects to filling machine or silo outlet
• Advantage: Fast and clean filling

Discharge Spout (Outlet Spout)

Located at the bottom of the big bag.

• Diameter: Ø250-450 mm
• Use: Direct connection to process equipment
• Advantage: Controlled flow and spill prevention

Double Spout (Full Spout)

Spout systems at both filling and discharge.

• Use: Closed-loop systems
• Advantage: Maximum contamination prevention

Operational Advantages

Key benefits of valve big bag usage:

• Automation Compatible — Integration with automatic filling/discharge systems
• Dust Emission Control — Dramatic dust reduction compared to open-top systems
• Hygiene — Minimized contamination risk in food and pharmaceutical sectors
• Spill Prevention — Material loss prevented, cost savings

Manual Intervention Minimization

Integrates with automatic systems.

Operational efficiency increases.

Occupational Safety

Dust leakage decreases.

Work environment becomes cleaner.

Occupational safety compliance becomes easier.

Closure Systems

Different systems for closing spout openings:

Rubber Band

• Economical and practical
• For short-term closure
• Easy application

Zip Lock

• Reopenable
• For situations requiring repeated access
• Medium-level sealing

Clip/Clamp

• Industrial applications
• Quick open-close
• High sealing
• Sealing Gasket: For critical applications requiring gas and dust tightness

Liner Integration

When liner (inner lining) is used in valve big bags, liner spout is integrated with fabric spout. This integration:

• Prevents liner from collapsing inward during operation
• Ensures complete discharge
• Increases sealing

Form liner or tabbed liner options provide optimized performance in spout systems.
